Subject: dt-bindings: net: Add rfkill-gpio binding
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=50071fdf0882a0449328c967f282ad7444d194bb;p=linux.git

dt-bindings: net: Add rfkill-gpio binding

Add a device tree binding document for GPIO controlled rfkill switches.
The label and radio-type properties correspond to the name and type
properties used for ACPI, respectively. The shutdown-gpios property
is the same as defined for ACPI.
